SPECIFICATION forming part of Letters Patent No. 683,635, dated October1, 1901.

Application filed January 23, 1901.

To all whom, it may concern:

Be it known that we, JOHN FRANCIS BOO- RAEM,a resident of the boroughofManhattan, in the city and State of New York, and BER- NARD J AOQUART,a resident of South River, in the county of Middlesex and State of NewJersey, citizens of the United States, have invented a new and usefulImprovement in Methods of Manufacturing Tiles, of which IO the followingis a specification.

Our invention relates to an improvement in the method of manufacturingtiles, and relates more particularly to the method of manufacturing thinstraight tiles in the wet process, whereby a thin straight tile maybesuccessfully manufactured which will be perfectly straight whencompleted.

' In the accompanying drawings, Figure 1 represents a view in edgeelevation of a brick-blank from which a straight tile is formed. Fig. 2is an end view of the same. Fig. 3 is a top plan view. Fig. aisa topplan view of the brick-blank after the straight tile portion has beennearly severed from the refuse portion of the blank. Fig. 5 is atransverse section taken in the plane of the line A A of Fig. 4. Fig. 6is a top plan view of the straight tile, and Fig. 7 is a top plan Viewof the refuse portion of the brick-blank after it has been severed fromthe tile.

By manufacturing thin straight tiles in the wet process there has beengreat difiiculty in keeping the tiles straight and avoiding warping thesame while being burned in the kiln.

5 To avoid this tendency to warp, it has been necessary to make the thintile very much thicker than the requirements of the tile demanded, thetiles being used only as a facing for walls, and the thinner the facingthe less space the tiles would take up in the room.

By means of the process to be hereinafter described We are enabled toproduce a very thin straight tile which is held against warping whilebeing burned, the refuse portion being very readily removed from thetile after it has been completed, which refuse portion may be againutilized in the manufacture of the brickblank, and because of its havingonce been burned it serves to lessen the (No specimens.)

shrinkage of the new brick -blanks to be formed from the-material.

We will proceed to describe our improved method of making thin straighttiles. A blank is formed of the full size of a brick by the wet processcommonly used. \Vhile the brick-blank is in its wet state the portion ofthe same which is to form the tile a is nearly severed from the refuseportion 12 of the blank by forming in the opposite faces of the blanktwo deep inwardly-extended kerfs c (1, extending the entire length ofthe blank, thus leaving a long narrow web of solid material connectingthe refuse portion with the tile portion. These kerfs 0 cl may be formedin any desired manner and at such points as will produce a tile of therequired thickness. The blank is then completely dried and burned in akiln in the usual manner, and because of the connection between therefuse portion and the tile portion the tile portion is abso- 7o lutelyprevented from warping, the tendency to warp being so great that therefuse portion of the blank is made very thick, so as to absolutelywithstand such tendency on the part of the tile to warp. After thebrick-blank has been completely dried and burned the refuse portion bmay be readily broken away from the straight tile portion a.

The process as above described enables us to save a large amount ofmaterial in the manufacture of each tile, thus serving the doublepurpose of producing a very thin facing-wall and alsosaving the cost ofthe additional material, which it has hitherto been necessary to utilizein the drying process for giving the tile sufficient body to prevent itswarping while being dried and burned.

\Vhat we claim is 1. The herein-described method of manufacturing thinstraight tiles in the wet proc- 9o ess to prevent the warping of thetiles consisting in forming a brick-blank, then nearly severing theblank to form a thin tile portion and a thick reinforcing refuse portionconnected therewith, then drying and burning the blank and finallyseparating the thin tile portion from the thick reinforcing refuseportion of the blank, substantially as set forth.
